Description

Technical Field

[0001] This utility model relates to a drying device, specifically a drying device for semi-coke samples. Background Technology

[0002] The main chemical reaction in calcium carbide production is CaO + 3C = CaC2 + CO. Semi-coke, as a carbon material, provides the carbon element required for the reaction and is one of the key raw materials for calcium carbide production. The quality of semi-coke has a direct impact on the yield, quality, and production efficiency of calcium carbide. To accurately determine the quality of semi-coke, it is necessary to conduct testing, and the sample preparation stage before testing is fundamental to ensuring accurate and reliable test results. Drying the semi-coke samples is a crucial step in the sample preparation process. Currently, existing sample drying devices on the market have several shortcomings in meeting practical needs when drying semi-coke samples. First, existing devices are deficient in terms of ease of operation. Placing and removing the material trays in most drying devices is cumbersome, requiring operators to enter the chamber, increasing labor intensity and posing a risk of burns from high temperatures. Furthermore, some devices lack effective safety protection mechanisms; when the pressure inside the chamber abnormally increases due to temperature rise, they cannot release pressure in time, potentially leading to device damage or even safety accidents. In addition, existing devices employ a crude drying method, with insufficient precision in monitoring the temperature and pressure inside the chamber, making it difficult to adjust parameters in a timely manner according to the actual drying requirements of the semi-coke samples, further affecting the drying effect.

[0007] Furthermore, the sealing ring is made of glass fiber.

[0008] Furthermore, a slide rail is provided inside the bottom plate of the box along the moving direction of the tray support, and a slide rod is slidably provided inside the slide rail.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 like Figures 1 to 2 The illustrated semi-coke sample drying device includes a chamber 1, one side wall of which is open, and a door 2 is provided at the open end of the chamber 1. The side wall of the chamber 1 has a sandwich structure, and nickel-chromium alloy electric heating wires 11 are uniformly arranged in the sandwich of the chamber 1. The nickel-chromium alloy electric heating wires 11 have the characteristics of rapid heating, stable heat and high heat transfer efficiency, which can quickly transfer heat to the interior of the chamber 1. At the same time, the sandwich structure helps the heat to diffuse evenly in the chamber 1, effectively avoiding the situation of excessively high or low local temperature in the chamber 1, ensuring that the semi-coke sample can be dried in a uniform temperature environment, avoiding the problem of sample property changes or moisture residue caused by uneven heating, significantly improving the quality of the dried sample, and providing a high-quality sample basis for subsequent detection work.

[0017] Three tray supports 3 are arranged from top to bottom inside the chamber 1. One end of the horizontally positioned tray supports 3 is fixedly connected to the inner wall of the chamber door 2, and the two sides of the tray supports 3 are slidably mounted in tracks 4 on opposite side walls of the chamber 1. A fiberglass sealing ring 5 is provided circumferentially at the open end of the chamber 1. The fiberglass material has excellent high-temperature resistance and sealing performance, allowing it to tightly fit the connection between the chamber door 2 and the chamber 1, effectively preventing heat loss and the entry of cold air from the outside, greatly reducing energy consumption during the drying process, and maintaining the temperature stability inside the chamber 1, providing a continuous and stable environment for drying the semi-coke samples. Furthermore, the excellent sealing performance prevents external dust and impurities from entering the chamber and contaminating the samples, ensuring the purity of the dried semi-coke samples and avoiding interference from impurities with subsequent testing results.

[0018] A slide rail 6 is provided inside the bottom plate of the box body 1 along the moving direction of the tray support 3. A slide rod 7 is slidably provided inside the slide rail 6. One end of the slide rod 7 is placed inside the slide rail 6, and the other end of the slide rod 7 is fixedly connected to the inner side wall of the box door 2.

[0019] To ensure the stable operation of the drying oven and meet the temperature requirements for sample drying, in this embodiment, a temperature sensor 8 and a pressure sensor 9 are provided on the oven door 2, and a pressure relief port is provided on the oven door 2, with a pressure relief valve 10 at the pressure relief port; the signal output terminals of the temperature sensor 8 and the pressure sensor 9 are both connected to the signal input terminal of the controller 12, and the signal output terminal of the controller 12 is connected to the signal input terminals of the nickel-chromium alloy electric heating wire 11 and the pressure relief valve 10, respectively.

[0020] Working principle: One side wall of the chamber 1 has an open structure, facilitating the entry and exit of the sample tray. The side wall of chamber 1 employs a sandwich structure, cleverly incorporating a nickel-chromium alloy heating wire. When current passes through the heating wire, it rapidly heats up, transferring heat to the interior of chamber 1, thus drying the sample. A horizontally positioned tray support 3 is fixedly connected at one end to the inner side wall of the door 2, while its two sides slide within tracks 4 on opposite side walls of chamber 1. This design allows the tray support 3 to smoothly enter and exit the drying chamber as the door 2 opens and closes. Operators can place and remove trays simply by opening and closing the door 2, eliminating the need to enter the chamber 1, significantly reducing labor intensity, improving operational convenience, and avoiding the risk of burns from high temperatures. To further improve the smoothness and stability of the movement of the door 2 and the tray support 3, a slide rail 6 is installed inside the bottom plate of the chamber 1, and a slide rod 7, which is fixedly connected to the door 2, is slidably installed inside the slide rail 6. To improve the sealing performance of the drying chamber, a high-temperature resistant, high-sealing glass fiber sealing ring 5 is installed circumferentially at the open end of the chamber 1, which can effectively prevent heat loss and the entry of external impurities, ensuring the stability of the drying process and the purity of the samples. After the door 2 is closed, the chamber 1 is engaged with the door 2 by a buckle, ensuring that the door 2 is tightly closed.

[0021] By installing a temperature sensor 8 and a pressure sensor 9 on the chamber door 2, the temperature and pressure inside the chamber 1 can be monitored accurately in real time, and the signals are transmitted to the controller 12. When the temperature inside the chamber exceeds the preset range, the controller 12 will promptly adjust the working state of the nickel-chromium alloy electric heating wire 11 to control the heating intensity and ensure that the temperature remains stable within a suitable drying range. When the pressure inside the chamber increases abnormally due to the rising temperature, the controller 12 will control the pressure relief valve 10 at the pressure relief port to open, releasing the pressure inside the chamber in a timely manner to prevent excessive pressure from damaging the device or causing a safety accident. This automatic monitoring and control mechanism significantly improves the safety and reliability of the device operation.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
